Up the swannee

This morning saw the teen leaving the house (and having to scrape ice off his car) clad in a shocking pink (highly flammable) floral shirt, a big 'fro, round sunglasses, jeans and flipflops. 
Today's theme translates as 'decades', so basically pick an iconic period in history, or a character (dressing as Hitler is verboten - I tried to talk the teen into being Winston Churchill but it was a no go) I saw Charlie Chaplin, possibly a caveman & definitely more hippies.
